摘要

Dear Editor, Plants establish beneficial symbiotic associations with arbuscular mycorrhizal fungi,which colonize the root cortex,building specialized structures called arbuscules that facilitate nutrient exchange.The association occurs following plant recognition of lipochitooligosaccharides (LCOs) from mycorrhizal fungi,which activates the symbiosis signaling pathway prior to mycorrhizal colonization.Here we show that SLR1/DELLA,a repressor of gibberellic acid (GA) signaling,and its interacting partner protein are required for the mycorrhizal symbiosis.
